springboot集成通用mapper的使用

引入jar包

<dependency>
    <groupId>tk.mybatis</groupId>
    <artifactId>mapper-spring-boot-starter</artifactId>
    <version>2.1.5</version>
</dependency>

啓動類MapperScan註解導包注意是tk.mybatis…

import org.springframework.boot.autoconfigure.SpringBootApplication;
import tk.mybatis.spring.annotation.MapperScan;

@SpringBootApplication
@MapperScan("com.bg.junior_brainpower_championships.mapper")
public class JuniorBrainpowerChampionshipsApplication {

實體類 @Table對應的表名 @Id對應的主鍵

@Table(name = "sys_column")
public class SysColumn implements Serializable {

    @Id
    private Integer id;

mapper層 需要繼承Mapper接口 泛型爲SysColumn

public interface SysColumnMapper extends Mapper<SysColumn> {
